Telecom DC Shunt

Telecom DC Shunts are typically rated for current ranges from 5A to 1000A or more, with voltage drop outputs commonly standardized at 50mV, 60mV, 75mV, or 100mV. They are constructed using manganin or nichrome alloy resistive elements for excellent thermal and electrical stability, mounted on insulating bases such as bakelite or epoxy resin. The terminals are designed for secure connections with copper busbars or cables, and the shunt body ensures minimal temperature drift for consistent accuracy. These shunts comply with standards such as IS 1248, IEC 51, or BS 89, with accuracy classes ranging from 0.1% to 1.0%. Their compact and rugged construction makes them ideal for panel mounting or integration into telecom DC distribution boards. Operating voltage is typically up to 75V or 110V DC, and they are engineered to withstand transient conditions while maintaining stable output for precise monitoring via digital or analog ammeters, controllers, or PLC system
